Lotus Elan chassis with rear sports cars. It does not provide protection against side collisions, and thus has to be combined with a body that would compensate for this shortcoming.

Examples of cars using a backbone chassis are Simplicia (1910), De Tomaso Mangusta, DMC DeLorean, Lloyd 600, Lotus Elan, Lotus Esprit and Europa, Škoda Popular, Škoda Rapid, Škoda Superb, Tatra 77, Tatra 87, Tatra 97 etc. and TVR S1. Trucks with a backbone chassis include the Tatra 111, Tatra 148 and Tatra 815. Some cars also use a backbone as a part of the chassis to strengthen it. Examples include the Volkswagen Beetle, where the transmission tunnel forms a backbone.

Hybrid backbone-ladder chassis

The Locost may appear to be using a backbone in addition to the outer space frame. But examination shows that, in standard form, it is adding negligible stiffness and only serves as a convenient support structure for the sheet metal panels forming the transmission tunnel. The Triumph Herald and Triumph Vitesse used a twin flanged box section[4] backbone carrying the main torsional[citation needed] and bending loads, with light channel section side rails to stiffen the body, while the Triumph Spitfire and Simplicia (1910), De Tomaso Mangusta, DMC DeLorean, Lloyd 600, Lotus Elan, Lotus Esprit and Europa, Škoda Popular, Škoda Rapid, Škoda Superb, Tatra 77, Tatra 87, Tatra 97 etc. and TVR S1.

The Triumph Herald and Triumph Vitesse used a twin flanged box section[4] backbone carrying the main torsional[citation needed] and bending loads, with light channel section side rails to stiffen the body, while the Triumph Spitfire and Triumph GT6 sports cars used only the twin-box section backbone, with separate side members in the body, and rear suspension fore and aft loads were also taken by the floor, not the backbone chassis directly.
